In each iterations print out:
– Iterate total five times over any two pairs sentence
– s-total(e) values for each pairs
– expected counts: count(e|f)
– total(f)
– estimate probabilities: t(e|f)
- Test your code with five pairs Turkish-to- English sentences
(5 parallel sentence, you can write these sentence yourself). Just
record result of the last iteration
- Compare your results with the Python IBM modules of the NLTK
library
